Not caching index.html

[goofblob]

Performance scenario:

On a current project getting index.html from Github Pages takes just over 300ms. And from disk cache about 30ms.

But getting it from the service worker takes 800ms+. So I do not want to cache index.html. I have achieved this with the following:

"globDirectory": "./dist", "globPatterns": [ "**\/*.{css,js}" ], "globIgnores": [ "./index.html" ],

However, workbox-sw still creates workbox.routing.registerNavigationRoute("index.html"); in sw.js. And because index.html is not cache, it is not served and the website simply does not work.

I have hacked my way around this by removing that line from sw.js manually -- by adding a sed -i /registerNavigationRoute/d dist/sw.js at the end of my build script. But this seems inelegant.

Is there a way to tell the plug-in to not do the registerNavigationRoute?

SEE END FOR THE REAL SOLUTION

The default configuration tries to stay (somewhat) compatible with the environment of the parcel dev server. It, as is common for a PWA app, serves index.html instead of a 404 error to enable client side routing (I guess). So to override the default

	navigateFallback: publicURL+"/index.html",
	"templatedUrls": {
		"/": ["index.html"]
	}

you need to set the configuration to :

"cache": {
	"globIgnores": [
		"index.html"
	],
	"navigateFallback": "undefined",
	"templatedUrls": "undefined"
}

Be sure to use the most recent version from the repository and not npm (the translation from json's "undefined" to javascript's undefined had to be added in febbdab):

"devDependencies":{
    "parcel-plugin-sw-cache": "mischnic/parcel-plugin-sw-cache"
}

---

EDIT: Apart from that "workaround", the real problem is that the file isn't getting cached properly.
Solution

"cache":{
    "ignoreUrlParametersMatching": [["#\/(?:video.*)?$"]]
}

This will rewrite the url, so that every subpage will also be served with the index.

Outstanding work!

Thank you. I hope you keep maintaining this. Parcel definitely needs it.
